Module: JetDatabaseSecure32 in Category Access/Jet Databases : Database from Total Visual SourceBook

' Example of modJetDatabaseSecure32
' Note: Workgroup security only applies to MDB databases and not ACCDB or ADP formats
'       This code is not supported in the 64-bit version of Access 2010 or 2013 due to the use of the 32 bit library MSJRO.DLL.
'
' To use this example, create a new module and paste this code into it.
' Then run the procedure by putting the cursor in the procedure and pressing:
'    F5 to run it, or
'    F8 to step through it line-by-line (see the Debug menu for more options)
